Se pretende destacar la importancia de la consideración del error tipo II y por ende la potencia de la prueba en la investigación científica, particularmente en el campo del diseño experimental. Se presenta su uso con base en un ejemplo hipotético y en un ejemplo real de un experimento en el campo agronómico, en el que se estudió el efecto de la concentración de fertilizante sobre la vida útil y la calidad de las flores de Phalaenopsis. Se concluyó, sustentando en una potencia de prueba alta, que aplicando fertilizante foliar en baja concentración es posible aumentar la calidad de las flores sin detrimento de su vida útil.

The objective of this work is to highlight the importance of considering type II error and therefore the power of the test in scientific research, particularly in experimental designs. Its use and determination are illustrated with both hypothetical and real examples in the agricultural field. In the latter, the effect of fertilizer concentration on quality and durability of Phalaenopsis flowers was studied. The conclusion, based on the high power of the test, was that a low concentration of fertilizer increases the quality of the flower, not affecting the durability. [ABSTRACT FROM AUTHOR]
